Background : This study was conducted to determine the optimal ginseng greenhouse shading material for minimizing heat injury and maximizing the yield of ginseng plants in an effort to develop a stable ginseng cultivation technology and contribute to popularizing ginseng greenhouse farming. Methods and Results : Three different types of greenhouse shading material were used: polyethylene (PE) film + black screen (95%), light scattering film + black screen (75%), and blue-white vinyl. Important experimental details were implemented in accordance with the Analysis Standard of Agricultural Test and Research set out by the Rural Development Administration. The average greenhouse temperature for the period of May through October was 20.0℃ under the PE film + black screen, 20.2℃under the light scattering film + black screen, and 19.7℃ under the blue/white vinyl. High average photosynthesis rates of ginseng plants were demonstrated by light scattering film+black screen (2.35 μmole CO2/㎡/s) and blue-white vinyl (2.38 μmole CO2/㎡/s), with the PE film + black screen showing a considerably lower photosynthesis rate (1.55 μmole CO2/㎡/s). Heat injury occurred in 0.3%, 10%, and 0.1% of the plants grown under the PE film + black screen, light scattering film + black screen, and blue-white vinyl, respectively. As for the roots, the blue-white vinyl outperformed the other shading materials in root length (25.7 ㎝), taproot length (5.9 ㎝), and the number of fine roots (23.2). The blue-hite vinyl also yielded the greatest root fresh weight (30.2 g), followed by the light scattering film + black screen (29.1 g), with the PE + black screen yielding by far inferior average weight (22.0 g). The highest crude saponin content was yielded by the light scattering film+black screen (16.61 ㎎/g), followed by blue-white vinyl (11.36 ㎎/g) and PE + black screen (11.0 ㎎/g). Conclusion : Comparing the effects of three different shading materials on greenhouse-cultivated 3-year-old ginseng plants, the blue/white vinyl outperformed two other shading materials in most of the growth characteristics, whereas the and the light scattering film + black screen yielded the highest ginsenoside content.

Background : The organic matter content of land clearing or soil brought from an other place is very low, less than 0.5%. However, the organic matter content of natural habitat soil and leader farmhouse soil was two to three times higher than that of general farmhouse soil. As a result, the yield of Gastrodia elata was higher than that of general farmhouse. Therefore, this experiment was carried out to investigate the yield of G. elata according to the application of green manure crops (GMCs). Methods and Results : This experiment was carried out in a soil with organic matter content of 0.5% in rain shelter greenhouse. The kind of GMCs are corn, Sudan grass, sorghum and oats, and the throughputs per 10 a were 2,000 ㎏, 2,200 ㎏, 1,500 ㎏ and 700 ㎏ of each. The soil preparation was carried out after treated of GMCs at least one month before G. elata was formally planted. As the results of these experiment, organic matter content in soils increased 4 - 5 times compared with before treatment. As a result, the yield of G. elata increased by 21 - 41% in all treatments of GMCs. In addition, there was 2 - 5% more G. elata of good merchantable quality. However, the soil temperature in the summer season period of 2016 (7.1 - 8.31) was 1.2 - 1.6℃ higher than the previous year. The day when the outside temperature was above 30℃ was 41 days. It doubled from the previous year. Soil moisture content showed similar tendency according to treatments. As a result, 20 - 30% of high temperature damage and 20 - 50% of putrefaction occurred, and the total yield also decreased by 20 - 30% compared to normal year. Conclusion : In conclusion, some organic matter is needed for cultivation of G. elata. Therefore, it is considered that it would be better to keep the organic matter content at 2 - 3% when the destination are managed, and to use corn or Sudan grass as the GMCs.

Background : This research was conducted to investigate the effect of organic compost treatment on growth and yield of organically grown ginseng seedlings(Panax ginseng C.A. Mayer) in growing medium. Methods and Results : The test cultivars was used a native species of Panax ginseng C.A. Mayer that most commonly cultivated in Korea. By seeding interval(3×3cm), seeds of Panax ginseng C.A. Mayer were sowed on March 29, 2016 . Bed size was 85 (W) × 1800 (L) × 30 (H) cm and shading material of plastic house was used blue-white vinyl. Growing medium composition(V/V) were mixed in a ratio of peat moss 60%, perlite 30%, vermiculite 10%. The mixing ratio of Organic compost was livestock manure compost (2%, V/V), mixed oil cake(2%, V/V), poultry manure compost (2%, V/V) and was applied to growing medium basal application. The emergence rate of ginseng seedling was contorl 95.7%, livestock manure compost 97.0%, press cake 92.3%, poultry manure compost 94.2%. Shoot growth characteristics of ginseng seedlings did not show a significant difference in plant height, stem length, stem diameter but shoot fresh weight was higher tendency in livestock manure compost(0.34 g/plant) in comparison to control(0.26 g/plant), mixed oil cake(0.29 g/plant), poultry manure compost(0.27 g/plant). Similarly, root fresh weight was higher tendency in livestock manure compost(0.52 g/plant) in comparison to control(0.33 g/plant), mixed oil cake(0.47 g/plant), poultry manure compost(0.43 g/plant). Root length was in control 10.2cm, livestock manure compost 11.8cm, mixed oil cake 8.9cm, poultry manure compost 8.6cm. As mentioned above, the reason that root length is shorter in mixed oil cake, poultry manure compost is thought to be due to the influence of gas injury. Conclusion : Growth characteristics of ginseng seedling showed a good growth trend in the organic compost treatment groups , especially livestock manure treatment root fresh weight increased 57% compared to control group. However, early defoliation phenomenon occured at mixed oil cake, poultry manure compost in late June. This is thought to have occurred by the disturbance of gas such as ammonia gas, nitrous acid gas. Therefore, if you use mixed oil cake, poultry manure compost to cultivate ginseng seedling, it is expected to pay attention to the damage caused by the gas disturbance.

In order to produce the high quality of dried-ear mushroom, various drying methods such as hot-air drying at 40~80˚C, freeze drying and drying in vinyl house were carried out. Drying hours of hot-air drying, freeze drying and drying in vinyl house were 12.5~21.5, 36.0 and 72.0 hrs, respectively. Vitamin D2 content of sample was the highest as 6.77μg/g DW in drying in vinyl house and then followed by freeze drying as 5.90μg/g DW and hot-air drying as 1.89~5.01μg/g DW. After dry, external appearance and color of mushrooms applied hot-air drying and drying in vinyl house were better than freeze-dried one. After rehydration, water uptake of sample in drying in vinyl house and hot-air drying at 50~60˚C were 17.8 and 19.3~21.0 times, respectively. The methods of drying in vinyl house and hot-air drying at 50~60˚C also led to high hardness, good shape and resilience. As the results of production of dried-ear mushroom with high quality, we suggest that the best method for drying is the drying in vinyl house due to not only high vitamin D2 content, good external appearance and color after drying but also high hardness and good shape after rehydration.

The average and maximum temperature were 29.5℃ and 33.2℃ at 2:00 p.m. respectively, in the plastic-filmhouse covered with shade net, and both of temperature were lower 0.6℃ and 1.3℃ than those of conventional shade. Lighttransmittance was 14% in the plastic-film house, while 9.9% in conventional shade during growing season from May toOctober. Withering time of aboveground part was on October 3rd in conventional shade with 60% of withering leaf, while itwas on November 10th with 3.7% of withering leaf in the plastic-film house, about 40 days longer survival. The main diseaseincidence were 15% of anthracnose, 17% of leaf spot, 5% of phytophthora blight and 3% of gray mold in the conventionalshade, while 0~0.1% disease incidence and 95% of emergence rate in the plastic-film house. The growth in the above-ground and underground part of ginseng was totally better, particularly characteristics affecting yield such as root length,main root length and diameter in the plastic-film house . The fresh weight was increased by 128% compared to the conven-tional shade and harvested roots per 3.3㎡ were 36 roots in the conventional shade and 58 roots in the plastic-film house andfuthermore yield per 3.3㎡ was increased by 216% compared to the conventional shade. As covering materials, the ricestraw in the plastic-film house was excellent. The ginsenoside contents affecting the quality of ginseng were higher in theplastic-film house indicating 0.333% of Rg1, 0.672% of Rb1, 0.730% of Rc and rate of red rusty root was less than4.0~6.1%. Above the results, the quality of ginseng grown in the plastic-film house covered with shade net was improvedthan that of the conventional shade.

When ginseng seedlings are cultured in paddy fields, quality degradation and yield reduction are induced by severe plant loss with chlorosis on leaves occurred physiological disorder by excessive salt and poor drainage, rusty-root occurrence, and root rot etc. Accordingly, in order to solve these problems, this study was performed to investigate the treatment method, concentrations and time of activated ion calcium as environment-friendly agricultural materials. Activated ion calcium is an enriched and purified water-soluble mineral calcium component for absorbing quickly into plant as a highly functional calcium and it is an alkaline calcium of 37% (370 ml/1 l) concentration with pH 13. Treatment method was that ginseng seeds were sown after removing water in the shade after seed immersion for 1 minute with active ion calcium of 20-fold diluted solution, and then irrigated 4l per 3.3 m2 with 200-fold, 400-fold, and 600-fold diluted solution before emergence on late March, and supplied 1 time on leaves with 500-fold diluted solution in June and July respectively. The disease rate by treatment of activated ion calcium was that on the treatment of soil irrigated with 200-fold diluted solution compared to non-treated soil, damping-off was 33%, anthracnose was 100% reduced and the occurrence rate of rusty-root was 30% reduced. In addition, when active ion calcium of 200-fold diluted solution were soil irrigated, first and second grade ginseng were respectively 26% and 22% produced more, compared with control.
